45 (1 + .2) = $ 54
(x+3)/3 = x/3 + 3/3 = x/3 +1
so x/3 + 1 = (y+2)/2
x/3 = (y+2)/2 - 1
Proprtional triangles so
47/82 = x/73.8
x= 42.3 m
The sides of the larger polygon are all 4 times larger then the smaller, so
x-3 = 4(2.5)
x-3 = 10
x=13
30 / 5/8 = 30 x 8/5 = 48
A ratio of 4:9 means 4/13 are childrens meals
13/4 x 36 = 117 meals total
The area of a circle is given by pi x r^2
diameter = 14 then radius (r) = 7
area = pi x 7^2 = 49 pi
-14 + 5u = -9u add 9u to both sides
-14 + 14u = 0 add 14 to both sides
14u=14 divide both sides by 14
u=1
x/9-6>-3 add 6 to both sides
x/9 > 3 Multiply both sides by 9
x> 27
